The letter tiles W, I, S, D, O, M are placed on a box. Without looking, Abby picks a letter tile from the box. What is the probability that the letter she picks is a vowel? Write your answer in the simplest form of a fraction.

Answer 1

There are 6 letter tiles in total, and 2 of them are vowels (O and I).

Therefore, the probability that Abby picks a vowel is 2/6 which simplifies to 1/3.

So, the probability that the letter she picks is a vowel is 1/3.

Answer 2

The sample space of an experiment is S={1,2,3} . Each outcome is equally likely to occur with a probability of 1/3 . What is the probability of picking number 2 or 3? Write your answer in the simplest form of a fraction.
